Abstract: Many constitutive models have been developed to describe hydromechanical characteristics of unsaturated soils. However, most models lack the capability to adequately simulate the change of the yield stress with suction, ...

Abstract: The small-strain shear modulus of soils is a key parameter in the design of geotechnical systems and analysis of the soil–structure response to earth and earth-supported infrastructure. However, the small-strain shear ...

Abstract: A major concern for projects involving deep excavations in urban areas is the response of adjacent buildings and utilities to excavation-related ground movements. Unfortunately, a purely theoretical approach to estimating ...

Abstract: A three-story school supported by shallow foundations was affected by an adjacent 12.2-m-deep excavation in soft clay in which the excavation support system was a 0.9-m-wide secant pile wall braced by both cross-lot struts ...

Abstract: Excessive crosstie wear and abrasion and ballast wear and fouling are fundamental problems contributing to inadequate railroad track performance. This adversely affects the attainment and long-term maintenance of desired ...

Abstract: Fly ash is the most generated coal combustion by-product (CCP) and causes the most substantial disposal issues. The current practice of landfilling these materials is costly and ultimately reduces available landfill space. ...

Abstract: Understanding fundamental track behaviors under dynamic load conditions is important to optimize design practices and achieve high-quality track performance. The American Railway Engineering and Maintenance-of-Way Association ...

Abstract: Since the 1960s, researchers have continued to develop new methodologies and algorithms in support of the planning, design, and management of water distribution systems. While initial research focused on modeling the ...
